<< Previous - Next >>

Columbus Instruments' PEGAS 4000MF Gas Mixer is a multi-gas mixer, which can blend from 2 to 4 gasses in a precise mixture available upon demand. The PEGAS 4000MF uses thermal mass flow controllers to provide an exact flow of each component gas. The system is equipped with an internal microprossor to perform all of the needed calculations and to provide signals to the flow controllers. The user only needs to enter the total flow and the concentration of each component gas. Front panel rotometer shows flow of mixed gas. External input for contact closure control to shut off gas flow. Options available: Remote control by a PC via RS-232 serial connections and user-programmed overpressure shut off.
